Botanists are working on an ambitious project to restore 1 million hectares (2.5 million acres) of degraded land in South Africa that were previously covered by thickets of the indigenous succulent spekboom (Portulacaria afra).
Countries need to fulfill their commitments to restore 1 billion hectares of degraded land by 2030 to avert dangerous climate change, according to a new report from the United Nations Environment Programme and the Food and Agriculture Organization.
